Commento su Esodo 10:13

ורוח הקדים THE EAST WIND — It was an east wind that brought the locusts because that came (blew) from the direction opposite to it (to Egypt), since Egypt was in the south-west, relative to Palestine, as it is explained in another place (Numbers 34:3).

ורוח הקדים נשא את הארבה, “and this easterly wind carried the locusts.” Seeing that an east wind is a blast of hot air, as we know from Jonah 4,8, where the effect of this hot easterly wind on Jonah’s state of mind is described, and it is the custom of locusts always to make their appearance when it is hot, as we already know from the prophecy of Nachum 3,17 מנזריך כארבה וטפסריך כגוב גבי החונים בגדרות, ביום קרה שמש זרחה ונודד ולא נודע מקומו אים, “Your guards were like locusts, your marshals like piles of hoppers which settle on the stone fences on a chilly day; when the sun comes out, they fly away and nobody knows where they are.” When G’d would want the plague to disappear, all He had to do was to command a west wind to that region.

וה' נהג רוח קדים, “and G’d guided an easterly wind, etc.” As on previous occasions, the letter ו at the beginning of the name of G’d is an allusion to the celestial tribunal working together with G’d. An easterly wind is perceived as a forerunner to disaster striking on earth. We find that wind in evidence in 14,21 prior to the Egyptians drowning in the sea after the sea had been split to allow the Israelites to cross safely. Jeremiah 18,17 wrote concerning the surviving tribes of Yehudah and Binyamin “I will scatter them in front of the enemy like an easterly wind.” Concerning the other ten tribes (prior to their exile) Hoseah 13,15 writes: “a blast of the easterly wind from the Lord will come blowing up from the desert and it will dry up its fountain and his spring will be parched.” Describing Israel going into exile, Isaiah 27,8 writes: “assailing them wih fury unchained, His pitilesss blast of the easterly wind bore them off on a day of gale.” There are more such quotes to be found in the Bible pertaining to an association between an easterly wind and disaster.
